Title: Estimering av strømningshastigheter fra multiple hydrokarbonreservoarsjikter inn i en produksjonsbrønn
Inventor: WOODS ANDREW W
IPC: G01F1/688
Filed: 2014-07-16
Abstract: Det tilveiebringes en datamaskinimplementert fremgangsmåte for å anslå strømning av fluid inn i en produksjonsbrønn som løper inn i et reservoar omfattende fluid, idet brønnen omfatter et sentralt rør og et ringrom som omgir det sentrale røret. Ringrommet er forbundet til reservoaret for å motta fluid ved ett eller flere innstrømningssteder. Det sentrale røret har minst ett innløp, anordnet for å la fluid strømme fra ringrommet inn i det sentrale røret, og er anbrakt nedstrøms av det ene eller de flere innstrømningsstedene. Produksjonsbrønnen omfatter ytterligere én eller flere innretninger som er anordnet for å måle en temperatur på fluid innenfor ringrommet ved en flerhet punkter langs ringrommets lengde. Fremgangsmåten omfatter å: motta temperaturdata fra den ene eller de flere innretningene som er indikative for en temperatur på fluid ved en flerhet punkter langs ringrommets lengde; identifisere en endring i temperatur på fluid som strømmer innenfor ringrommet, på grunnlag av de mottatte temperaturdataene ved flerheten punkter; anvende en modell for å anslå varmeovergang fra det sentrale røret til fluid som strømmer innenfor ringrommet, idet modellen er innrettet slik at varmeovergangen er forutsatt å være i det vesentlige konstant langs rørets lengde; og anslå en rate ved hvilken fluid strømmer inn i ringrommet fra reservoaret ved et første innstrømningssted, på grunnlag av den identifiserte endringen i temperatur mellom punktene og den anslåtte varmeovergangen.

Title: Mesh made of monofilaments
Inventor: PINTZ HEIKO
IPC: D04H3/14
Filed: 1999-01-08
Abstract: The invention relates to a wide-meshed textile grating for providing reinforcement in civil engineering applications, especially for reinforcing ground layers. The inventive grating consists of groups of weft and groups of warp threads which have been preferably woven or knitted together. Each group of threads is at least 8 mm away from the adjacent parallel group of threads and the individual threads making up each group are made up of highly resistant yarns. The groups of weft threads and groups of warp threads of the textile grating are covered with a polymer coating. The aim of the invention is to provide an easy to handle grating with a low specific weight which digs into the ground layers to be reinforced more effectively. To this end, the polymer coating contains evenly distributed gas inclusions so that it has a foam-type structure. The invention also relates to a method for producing a textile grating of this type, characterised in that a foaming agent is added to the plastic compound used to form the polymer coating. Said foaming agent forms gas inclusions whilst the polymer is setting.
